REINFORCED RAIL-ANCHOR.

To all whom it may concern:

' Be it known that I, BENJAMIN \VOLHAUP- ran, a citizen of the United States, residing at New Rochelle, in the county of West- -chester and State of New York, have inventedcertain new and useful Improvements in Reinforced Rail-Anchors, of which the following is a specification.

This invention relates to the subject of rail anchors designed to prevent longitudinal creeping of railroad rails, and'particularlv to a reinforced construction for devices of this character,

As 'is' well known, a rail anchor must possess certain characteristics to satisfy the exacting demands imposed thereon. One of these characteristics is that the device must be so constructed and arranged thatritmay,

with a minimum use of metal. It is therefore a distinctive object of the. present invention to provides. reinforced rail anchor de vice possessing the desirable character stics with maximum strength throughout.

Wit-h these'and other objects in view which will beapparent to those familiar withtthe art'theinventionj consists in the novel fea- 'tures of improvement hereinafter more fully described, illustrated and claimed.

The essential feature of the invention, in: volved inan I-bar formation of rail anchor body, -is necessarily susceptibleofstructural modification without departing from the scope of the invention, but certain preferred andpractical embodiments of the device are shown in the accompanying drawings, in WhiCh2.- I Figure lis aside view of a rail anchor having incorporated therewith the improve Patented Sept. 24, 191s.

- As-findicated, a distinctive feature of the present'invention is the provision of an adequatelyreinforced rail anchor structure possessing the desirable characteristic of lightness, while at the same time having the metal distributed therein in such it is most needed. This permits the anchor to withstand the severe service conditions to which it is subjected, without impairing its hold upon the rail.

To thisend, it is proposed, according to the present invention, to utilize as a basis of construction an I-bar distribution of metal for the body of the anchor. That is to say, in carrying forward the present invention, the body of the anchor, regardless of its rail engaging or rail gripping features, is constructed on the principle of an I-bar. This design of bar provides a most effective distribution of metal, While at the same time-admitting of a relatively light construction. In other words, with the same amount of metal the I-bar formation pr0- a manner as to provide a maximum reinforcing effect Where vides a stronger device and.

Also,-an I-bar shape affords o tunity, with even a decrease ofweig transpose the metal from the side ar vantageous result of placin reinforcement on the bar where most nee ed to better-"11B- sist the strains and loads imposed upon it. This reinforcement also enables the bar to be clamped upon the rail to an extreme-degree of tightness without danger'of break. ing or fracturing the bar.

By way of illustrating the applicatioiilof the I-bar distribution of metal to the-"co1istruction of a rail anchor, thereiis shown in Figs. 1 to5 inclusive of the drawfigs a cli t pe of rail anchor adapted to forcib y .d riven upon thewedge-like rail fl"ange,'-*and held thereon by thespring gripping: force produced through the distortion-of the clip when forced into place. The s ring-clip v provided with a bowed portion B having at approximately the terminals of its are or how the projecting gripping elements l t- 14 referred to, so that the device will have a more effective gripping action by reason of providing a three-point contact with the rail flange. In thisstructure, it will be seen that the opposite members 12 and 13 of the spring clip constitute spring clamping jaws which are intended to haven direct gripping or bitingfengagement with both the upper and lower surfaces of the rail flange, and when the clip is driven on to the. wedgeshape rail flange there will be a tendency of the bowed portion B to flatten out more or 1 less, resulting in augmenting-the biting engagement' of the e1ements'14'1i4 as the clip iscrowded inwardly upon the flange.

The clip-type of structure above'described may bemost advantageously made of a bar of high-carbon steel suitably, tempered and which has -an I-bar distributiomof' metal, namely, a relatively thin web portion a and oppositely entending flanges bconne'cted by the Web portion and combiningtherewithto provide -a bar of relatively light weight but of maximum strength by reason of the reinforcement given thereto by the flanges along its edge portions.

To further illustrate that the invention is susceptible of variation to meet different requirementsandadapted to different forms a ofifail anchors there is illustrated in Figaq '11 to l i'inelusive a'difi'erent type of anchor 1 and a modification inthe I-bar distribution fofn'netal.v Referring in detailto this modific ation, shown in said Figs. 11 to 14 i 1;,

clusive it will be observed that there is shown in this illustration'a springclamp i =-typ'e of anchor which primarily consists of a bar of spring steel, designated generally by the numeral 16 which is subjected to bonding operations to form at one end of the bar a rail engaging clip 17 provided 3 ciip members is designed to have a substantial clearance from the rail base and from the outer edge of the rail flange. Also, in

.this type of anchor the spring bar 16 has formed at an intermediate point an up:

standing or bowed portion 20 constituting a fulcrum element adapted to engage the base of the rail, and atom side of this fulcrum element the bar'is extended into a lever arm 21 formed at one end with the looped lifting member 22, extending, with a free clearance, about one of the rail flanges and having a top member 23 overlying the rail flange and adapted to be forcibly engaged by an adjustable wedgekey 24 or equivalent tensioning device. This wedge-key 24 is interposed between the under side of the top part 23 of the lifting member 22, and the upper side. of the rail flange, and, when driven tightly home, exerts a lifting force on the member 22 and the lever arm 21, with the result of placing the entire bar under spring'jtension and thereby causing a tight gripping of the a practical limits,

rail at the fulcrum element 20 and by the upper clip member 18. The spring action of the spring-clamp type of anchor 16 is made entirely effective by having the metal of the bar so distributed as to withstand, to any degree Within thereof through the tightening of the vice. That is, the present invention provides for distributing the metal throughout the anchor body 16 in an I-bar formation, whereby the body of the bar is formed with a relatively thin web a, and the oppositely extending flanges 7). It will thus be seen that the anchor body is provided with sub-. stantial reinforcing flanges at both'edges and with a relatively thin and light web portion a. connecting said flanges, and combining therewith to make a relatively light structure having great strength along its edge portions, and at the places where most needed in an anti-creeper device.

In the embodiment of the invention above described, a uniform I-bar distribution of metal is maintained throughout the bar body, that is to say, at any point in the length of the body as shown by Figs. 12 and 13 of the drawings, the section is of uniform size as to all dimensions, depth,

1 width, and thickness.

Other modifications and adaptations of the invention will now be clear to those familiar with the art without further description, and it will be understood that changes in the form, proportion and minor details any of the advantages of the invention.
